I m a freshman in high school, please give me some advice! Thank you! 10

Lay a good foundation in the first year of high school, and it turns out that you don't want to think about playing in the first year of high school, the second year of high school, and the third fight.

If you work hard in the first year of high school, it will be easy to learn in the future.

At the beginning of the first year of high school, there is generally a big gap between mathematics and physics and junior high school courses, and they are basically not connected. So these two subjects take a lot of effort.

Are you studying literature or science?

If you want to study literature, politics is more difficult to understand, because it is different from casual learning in junior high school, so the first chapter is important. Geography is a difficult part of the whole high school stage, and learning physical geography is an abstract drop, but don't be afraid, it's still easy to learn.

In terms of theory, chemistry is not too difficult, and some courses are junior high school. Physics is different, the exercises in the book are simple, and the information is big, so lay a good foundation.

The most important thing is mathematics, many people are successful in mathematics, and failure is also mathematics. The function of the first (first) is important, and the series is more flexible. I personally think that it is not difficult to go up, vector is a tool, and it must be learned well.

Before high school came, you asked for a way, and it seems that you are a good student who loves to learn.

Have a plan to study, be too blind, have a regular schedule and so on. Well, learning methods are very important, and these are waiting for you to find out for yourself.

The first year of high school is mainly to complete a transition, the depth and breadth of learning in junior high school and high school are very different, after the first year of high school, we must gradually find out a new learning method suitable for ourselves, and after the scrutiny and improvement of the second year of high school, so as not to be in a hurry in the third year of high school.

I just finished my first year of high school, and my experience is that the first year of high school pays attention to cultivation, and there must be a process of adaptation from junior high school to high school, so you must pay attention to the accumulation so that you will not feel too tired in the second year of high school, remember not to let the problems pile up, otherwise it will not be easy to understand them in the future.

There is an obvious difference between high school and junior high school, and you have to re-explore your own learning methods, and the most important thing is that you must be down-to-earth in high school learning, consolidate your knowledge step by step, and have the spirit of never giving up.

The distance between the two parallel screening lines is |-6-3|2=9 2, since l is cut by two parallel lines and the length of the line is 9, so the angle between l and the two flat digging Gyeongju line is 45°, so let the slope of l be k , then |(k-1)/(1+k)|=tan45°=1 , the solution is k=0 or the difference between k=0 or the difference between k=0 and the equation for the straight line is y=0 or x=1

Let the intersection point of the straight line l and two parallel lines, use the formula of the distance between the two points equal to 9, and substitute the collapsed line to find the coordinates of the intersection point, and then use the three-point coordinate formula.
